The Horde Application Framework is a modular, general-purpose Web application framework. It provides an extensive array of classes that are targeted at the common problems and tasks involved in developing modern Web applications.

PHP MIME Mail decoder class is a PHP class to parse and decode MIME email messages. It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format. It can decode messages read from files or data strings. The bodies of multipart messages can be decoded into distinct sub-messages. Optionally, the message body data can be saved to separate files, so the class can handle messages larger than the available memory. The parser can tolerate some syntax errors in malformed messages that are not compliant with RFC 2822.

vTemplate is a PHP class that is intended to make
splitting PHP from HTML a simple and natural
task. It has easily understandable syntax that is
much easier to use than other template classes.
It compiles a template into native PHP code using
one PCRE call, thus the parsing is extremely
fast. It also has powerful caching and debugging
classes to extend the functionality.

Table Class allows you to create highly dyanamic
HTML tables easily and quickly. It supports CSS,
any number of arbitrary tags, and creating tables
inside tables. This class is useful for
implementing intensive reporting features. Table
Class is faster than using and parsing traditional
HTML templates because the class works completely
in memory, storing all the table data in several
comprehensive arrays, while not compiling to HTML
until you want it to. This allows for dynamic
editing of any attribute of any element. Rows and
columns can be easily added and subtracted at any
time, and row contents can be added simply by
passing an array.
